I recently bought this Bob Dylan signed photo after some deliberation. However today, when it arrived someone on another forum told me it was fake. They also told me to come here as you guys were the best at authenticating autographs so please help me.

This was the story the seller gave me about how it was obtained: "hello im a limo driver service an i used to drive the journelist around when he spent times on isle of wight his name was david castell an at that point he saw bob dylan at the festival an after festival he went on set of hearts of fire where pic an sign where done as for me getting it as a gift as im in to bob dylan"
Also I checked out his ebay profile and this is the only signed item/autograph he has ever sold so I don't think he's a faker.
